    They should be hardy in your area, so I'm not sure why the top growth died. However, English walnut trees are usually grafted, so the suckers coming back from the roots are from the rootstalk, so you don't want to propagate the tree from those.
    You can remove it by cutting down the dead growth and applying a stump killer.

    You need a grass-free area around your tree that extends to the canopy. Cover it with a couple inches of mulch. Your tree should not be getting your lawn fertilizers and weed killers. Especially avoid getting weed and feed on it. It has weed killers that could harm the tree.

    Generally, you want to cut closer to the end of dormancy, but while the tree is still dormant. This article will help:

    I understand they will ripen off the tree, but it may take about 5 weeks.
